My present invention has reference to a lubricating system between journals and dency to hardener any foreign substances which may have been let in the well or poclretfor the lubricant will be withdrawn therefrom when a new supply of lubricant is required. p

To the attainment of the foregoing, the improvement resides in the novel features of construction, combination and operative association of parts a satisfactory embodiment of which is illustrated by the accompanying drawings.

In the drawin s:

Figure 1 is an elevation partly in section illustrating my improvement employed in connection with the spindle bolt and the front axie of an automobile.

Figure 2 is a similar view but illustrating the improvement in connection with the springshackle bolt of an automobile.

Figure 3 is a sectional view on the line S3 of Figure 2.

' Figure 7 is'a view of the auger member employed in the construction illustrated in Figure 5.

Figure 8 is an end view of the anger as shown in Figure 7. I g I In the drawings and with reference to Figure 1 thereof, the numeral 1 designates the spindle bolt which is received through the spindle body bushing 2 on one end of of means forcing said lubricant betively simple construction, which will efthe spindle 3 for the frontaxle of an automobile, the forked end, of the front axle through which, thebolt 1 passes being indicated by the nume al at. p .lncarrymg out my invention I bojrea.

round opening partly through the bolt 1,.

i' rom theupper headed end thereof. The

opening, indicated by the numeral 5 is eccentricwitli respect to the axial plane of the bolt, the said bolt being notched, as at 6, in a line inwaidly of the bottom wall provided by the opening 5. The opening 5 provides a lubricant well and screwed in the stud opening at the outer and headed X end of the bolt 1, there is a sleeve 7. The

sleeve is designed to have arranged thereover a cap member 8. and this cap member carries an auger tlwhich is adapted to be received in the lubricant well. Qf course, a lubricant is fed into the well before the auger arrangedtherein and the cap Sis indented to provide a spring tooth 10 to be received in a depression 11 in the sleeve 7.

The auger is in the nature ofa tubular member which is centrally slotted throughout its length to a point at or adjacent its connection to the cap 8. One of the arms of the auger may be of a greater length than the otherand the said longer end being shaped to provide a cutting element or bit '12.

The cap 8 effectively closes the oil well,

and by turning the said cap the bit end 12 as well as the sharpened edges of the auger will scrape the well and remove therefrom any lubricant which has adhered thereto when the said auger is removed from'the well.

Vith a construction as just described it will be apparent that the employment of high power grease guns for lubricating the movable parts of a machine will be effectively dispensed with. V

In Figures 2, 3 and 1, I have illustrated my improvement in connection with the bolt 13 for a spring shackle 14;. In this instance the bolt 13 is formed from one of its ends with a round opening that provides an oil well 15, the said bolt having a notch 16 which communicates with the well. The well is arranged eccentric with respect to the axial center of the bolt. screwed in the opening 15 an outwardly eX- tending sleeve 17 provided on its top face with an opening 18. Arranged over the sleeve there is a cap member 19 that carries an anger 20 of, a similar construction to the The bolt has tions auger above described. The cap 19 has an opening 21 therethrough adapted, when the cap is turned, to register with the opening 18, and through these openings a lubricant may be poured which, of course, will enter the well and lubricate the elements 13 and 14. The cap is also formed with an indenture providing a spring teeth 22 which is designed to be received in the openin 18 when the cap is turned to close the said opening 18. By turning the cap 19 the bore of the lubricantwell 15 will be scraped and in this instance the cap and anger are only removed from the well when the scraping of such well is desired.

In Figures 5, 7 and 8 I have illustrated a further modification. In this instance a bolt or journal member 23 is provided with a well 24 disposed to one-side of the axial center of the said member 28, there being a notch 25 which communicates with the well.

The bolt member is received in a suitable bearing 26 and screwed in the well; at one end of the member 23. there is a lubricant receptacle 27. Screwed on the receptacle 27 there is a lubricant cap or cup 28 that carries an anger 29. In this instance, the anger is in the natru'e of a metal plate or bar having its free end sharpened to provide the same with a bit 30 and being provided from its edges or its opposite sides with round auger por- 31. This construction is employed when a heavy lubricant is fed between the stationary and movable parts.

The simplicity oi my construction and the advantages thereof will,it is thought, he pertectly apparent to those skilled in the art to which such invention relates when the foregoing description has been read in connection with the accompanying drawings.

Having described the invention, I claim:

1. The combination with a bearing having an oil well therein, provided with a passage to communicate with an element journaled on the bearing, of a means for feeding oil into the well and for scraping oil therefrom comprising an anger received in the well and contacting with the walls thereof.

2. The combination with a bearing having an oil well therein provided with a passage to feed a lubricant onto an element journaled on the bearing, of a means for feeding a lubricant into the oil well and for scraping the same therefron'i, said means comprising an auger received and revoluble in the well, said augerincluding a straight portion whose edges contact with the wall of the bore of the well and a curved portion which also contacts with the bore of the well, and the end of the auger received in the well being sharpened.

In testimony whereof I allix my signature.
